Consider a metal rod that is 8.894 mm in diameter and 4.952 m in length. The elastic modulus for this type of material is 112 GPa. A tensile load of 66,523 N is applied to the rod. Assuming that the material behaves elastically under this load.
(a) Calculate the length (in the unit of meter) of the rod under this load. Please keep three decimal with your answer, i. e., your answer should be in the format of x. xxx. Please do not include units in your answer.

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
